The present invention relates to a hookah heat distributing device for a water pipe, in particular a hookah.

PRIOR ART

In a water pipe, in particular a hookah, flavoured tobacco is smoked. The tobacco is heated by a hot medium such as coal. The heating causes the molasses previously absorbed by the tobacco to evaporate. The vapour produced is passed through a smoke column. A valve opening is attached to a water vessel, such that the vapour, which is conducted through water and cooled in this way, is conveyed via a hose and a mouthpiece to a person smoking.

From the prior art. devices are known with which the tobacco is heated by means of burning coals in order to release the molasses, in particular an aroma liquid, efficiently.

Such a device is described, for example, in WO 2014/016088 A1. In WO 2014/016088 A1, a portable water pipe is represented, wherein tobacco lies on a plate. The plate can be pivoted around a central axis, such that a first valve mechanism can be adjusted between an open position and a closed position. Furthermore, a second valve mechanism can be adjusted between and open position and a closed position by a rotation of a mouthpiece. Here, no drive device is provided, for example no electric motor, and no homogenisation of the heat distribution is achieved in this way.

WO 2017/178930 A1 discloses a consumable hookah article, which is arranged in a hookah head comprising an electric igniter. A substrate for forming an aerosol can be consumed individually or sequentially. Furthermore, the substrates rotate about an axis to align each substrate with an aerosol outlet opening opposite an ignited combustible heat source. Here too, no drive device, for example no electric motor, is provided to rotate the heating means, and the arrangement also does not serve to heat the substrate homogenously.

DE 43 28 243 C1 discloses a smoking or inhalation device for smoking tobacco or another smoking product, wherein the device comprises a hot air generator, an air inlet opening, a heating device, an air outlet nozzle, a storage vessel and a drive device. Ambient air enters the hot air generator directly through the air inlet opening and can flow past the heating device. The ambient air is thus heated. The air outlet nozzle is arranged above the smoking product that is introduced into the storage vessel. The smoking medium is selectively heated by the heated air via the air outlet nozzle. Furthermore, the drive device moves the storage vessel into a rotary movement in order to guide the individual partial quantities of the smoking product past the hot air flow of the outlet opening of the air outlet nozzle, wherein the drive device is configured as an electric motor. Here, it is neither a coal lighting nor a hookah.

DE 198 54 008 A1 represents an inhaler device having a combustion chamber, a rotatable disc and an opening, wherein an aerosol-forming material is provided in a substrate portion, and a heating means is provided in the combustion chamber. The disc can be rotated by an operating device, wherein the operating device can have an electric switch that causes the disc to rotate by means of an electric motor. The disc can be used to rotate the combustion chamber. No water pipe principle is described here.

DE 20 2015 004 479 U1 discloses a water pipe which proposes a coal plate between a smoke column and a cone valve. The coal on the coal plate can be arranged in such a way that the coal lies unevenly on the entire surface of the coal plate, i.e. on only three surfaces of the coal plate. No motor drive for the water pipe is stimulated.

In the known device, no drive device is provided for a coal lighting of a water pipe or a hookah in order to rotate the coal plate and/or the hookah head, such that the tobacco on the coal plate is heated homogeneously.

However, if the tobacco in the hookah head is heated inhomogeneously, this results in the problem that no intense flavour and only little steam can be generated. The coals can be provided unevenly on the coal plate, and the tobacco can be heated inhomogeneously too high or too little. If the coal plate and hookah head are at rest when heating the tobacco, it will allow a heat spot and an uneven combustion of the tobacco. In this way, the taste is negatively affected. Furthermore, a relatively long time is required to provide optimal lighting, which can spoil the pleasure of hookah smoking, especially for inexperienced users.

Based on the above-mentioned disadvantages of the prior art, the object of the invention is to reduce the disadvantages of the known arrangements.

The aforementioned object is solved by a hookah heat distribution device according to the independent claim. Advantageous developments of the invention are the subject matter of the sub-claims.

DISCLOSURE OF THE INVENTION

A hookah heat distribution device for a water pipe, in particular for a hookah, is proposed, wherein the hookah heat distribution device comprises a hookah head for receiving tobacco and a coal plate arranged on the hookah head, on which coal plate lighting coal is provided.

In accordance with the invention, it is proposed that a drive device is comprised which comprises a drive part, a drive Wheel and a rotor shaft, and a chassis is provided which is attached to the hookah head by a fixing device, in particular a fixing screw, and to the drive device by an adjustment device, in particular an adjustment screw, wherein the coal plate and the hookah head can be rotated relative to each other about a rotational axis by means of the drive device.

Between the coal plate and hookah head, a chimney attachment which has a chimney pipe can be arranged. Ambient air flows past the lighting coals and is heated. Through openings in the surface of the chimney attachment, the heated air enters the hookah head, thus the tobacco provided in the hookah head is directly heated by the heated air which exits through the openings. With the chimney pipe, excess heat is transported to the outside, such that heat accumulation can be avoided.

The hookah head and the drive device are connected to each other by the chassis. By means of the fixing device, e.g. a fixing screw or a fixing rivet, the chassis is fixed in place on the hookah head and attached to the drive device by means of the adjustment device, for example an adjustment screw. The chassis thus acts as a connecting element between the drive unit and hookah head and can be provided as a retrofit part for already existing hookahs or also integrated, preferably in one piece, into new hookahs.

Due to the relative rotation of the coal plate and the hookah head receiving the tobacco, a homogenisation of the heal distribution is achieved, in particular during a heating phase, such that the tobacco can be heated evenly.

Advantageously, in the hookah heat distribution device, an electric drive or a mechanical drive can be formed as the drive part of the drive device, such that the drive wheel can rotate around the rotary shaft. As a result of the coal plate and/or the hookah head being connected to the drive device, preferably the drive wheel, by means of a transmission, i.e. an element which transmits the rotational movement and which can also be used to change the speed between the drive part and the axis of rotation, the coal plate and the hookah head can be rotated relative to each other around the axis of rotation. As a transmission, a rubber band or a rubber roller can be arranged on the drive device, preferably on an axially extending outer surface of the drive wheel. Of course, a gearwheel connection between the coal plate or the hookah head can be used, wherein further preferably in the drive device, preferably the drive wheel can be designed as a gearwheel, via which the coal plate and the drive device can be set in rotary motion with each other.

In the hookah heat distribution device according to the invention, the coal plate can be rotated around the axis of rotation with respect to the hookah head. Since the coal plate is coupled to the drive device or to the drive wheel via the transmission, the coal plate can be driven indirectly by the drive device. If the rubber band is used as a transmission, the coal plate and the drive wheel of the drive device rotate in the same direction. If a rubber roller or a gearwheel connection is used as a transmission, the coal plate and the drive wheel rotate in opposite directions.

Alternatively, it is conceivable that the hookah head is coupled to the drive device or the drive wheel by the transmission, such that the hookah head can be rotated. Thus it is achieved that the hookah head can be rotated around the axis of rotation with respect to the coal plate. Similarly, the rubber band, the rubber roller and the gearwheel connection can be used as a transmission.

The coal plate and the hookah head can also rotate simultaneously in opposite directions. In this case, for example, one or more rubber bands can be formed as transmissions, wherein one rubber band is arranged directly on the axially extending lateral surface of the coal plate, and a further, crossed rubber band is arranged on the axially extending lateral surface of the hookah head. A gearwheel transmission or similar can also provide a combined, counter-rotating rotation of the coal plate and hookah head.

It is advantageous that the coal plate and the hookah head can be rotated relative to each other during smoking. As soon as the drive device is switched on, the hookah head and/or the coal plate, as well as the coals lying unevenly thereon, rotate. Thus, the tobacco in the hookah head can be homogeneously heated by means of the air heated by the coals. This makes it possible to generate an intense flavour and a lot of vapour.

Furthermore, it is advantageous that with the hookah heat distribution device according to the invention, not an excessive amount of heated air reaches one point in the hookah head. This avoids a heat spot and a combustion of tobacco at this point, which results in a bitter taste and can release unhealthy combustion residues. This can also prevent self-ignition of the hookah head. Furthermore, it is advantageous that through the use of the hookah heat distribution device according to the invention in the water pipe or hookah, the time for optimum lighting and until intensive tobacco enjoyment can be shortened.

In an advantageous development, the rotary shall of the drive device can be operatively connected to the coal plate and/or the hookah head by a transmission, preferably by a drive wheel. The drive device comprises the rotary shaft on which the drive wheel is mounted. As a drive part, an electric drive or a mechanical drive can be provided. The drive wheel can hereby be driven by the drive part. By means of the transmission, e.g. a rubber band, the operative connection between the coal plate and the drive wheel can be provided, thus the coal plate can be rotated. Furthermore, the hookah head can be connected to the drive device via the operative connection, wherein the operative connection is preferably made possible by a drive wheel. In this way, the hookah head is rotated in such a way that the hookah head rotates in the same or opposite direction of rotation of the drive wheel, depending on the transmission with respect to the drive wheel. Furthermore, it is possible that the coal plate and the hookah head are simultaneously connected by the transmission to the drive device, preferably to the drive wheel. Thus, the coal plate and the hookah head rotate simultaneously in opposite directions under the effect of the drive device.

In a further advantageous development, an electric drive, in particular an electric motor, can be provided as a drive part. Thus, a DC motor or an AC or three-phase motor can be used as the drive, wherein a DC motor would be preferable for easier construction. By controlling the speed of the electric motor, a rotation speed of the coal plates and/or the hookah head can be changed; for example, by a simple voltage control or an electronic control, a speed control can be achieved. Thus, the time for optimal heating of the tobacco is influenced. The faster the coal plate and/or the hookah head rotate, the more homogenously the tobacco is heated in the hookah head. Thus, more steam can be generated at the higher speed of the electric motor in a given period of time.

In a further advantageous development, the electric motor can be connected to the power grid by a cable in order to drive the electric motor. In this case, the power grid is provided as a power supply. Thus, an alternating current is fed to the electric motor via the cable, wherein by means of interconnected drive electronics, a direct or alternating voltage for operating the electric motor at varying speeds can be provided very easily. The drive electronics can be equipped with a switch unit which makes it possible to conveniently switch the hookah heat distribution device on or off and to set the speed of the electric motor. Thereby, it is possible in a simple way to achieve a predetermined heating time of the tobacco. Thus, a specific quantity of steam can be generated.

In a further advantageous development, a preferably rechargeable battery can be provided as the power supply for the electric motor. Thus, a direct current is provided by the battery to drive the electric motor. In this case, a DC motor can advantageously be used. Furthermore, the battery can be designed not only as a primary cell, but also as a secondary cell, A lithium-ion accumulator, for example, can be used as a secondary cell. If a primary cell, e.g. an alkaline-manganese battery, is used as an energy source, after a discharge a new primary cell must be provided for the hookah heat distribution device. Compared to the primary cell, it is advantageous that the secondary cell can be recharged after discharge. Thus, the secondary cell is recyclable and environmentally friendly.

Advantageously, the power supply can provide a charging possibility for a mobile phone as a battery or mains connection, in particular a USB connection and/or an induction charging pad.

In a further advantageous development, the electric motor and/or the battery can alternatively or additionally be connected to a solar cell to provide electrical energy for driving the electric motor. A thin-layer cell or a multi-cell can be used as an energy source. With a photovoltaic effect, the solar cell can convert sunlight directly into electrical energy. This generates a DC voltage or direct current from the solar cell. Advantageously, the DC motor can be arranged as a drive part of the drive device, wherein drive electronics are connected to the solar cell by means of a cable. Alternatively, it is conceivable that an AC motor or three-phase motor is used as the drive part. Thus, an inverter can be provided between the solar cell and the three-phase motor, such that the direct current generated by the solar cell can be converted into an alternating current.

Furthermore, a rechargeable battery can advantageously be provided between the electric motor and the solar cell. Thus, the rechargeable battery can be directly charged by the solar cell as soon as the battery capacity is exhausted. Furthermore, it is advantageous that the use of solar cells is free of charge compared to other energy carriers. In addition, the use of solar cells does not generate any exhaust gases, as is the case with fossil energy sources; in this respect, the use of the solar cell is environmentally friendly and follows the green energy concept.

In a further advantageous alternative or additionally combinable development, a mechanical drive, in particular a spring mechanism, can be comprised as a drive part, wherein the spring mechanism can preferably be wound with a winding shaft. The spring mechanism can comprise a spring and a winding transmission having a tensioning device, wherein the spring is usually helically wound. The spring can store potential energy that can be converted into rotational motion by means of the winding transmission. By rotating the winding shaft, the spring mechanism can be wound, for example, via corresponding winding wheels of the winding transmission. Thus, the mechanical energy or potential energy can be stored in the spring mechanism. Furthermore, the spring mechanism can be coupled to the rotary shaft, wherein the drive wheel is mounted on the rotary shaft, such that the spring mechanism and the drive gear can be connected to each other. Thus, the drive wheel can be rotated in a rotatable manner by the stored mechanical energy of the spring, This means that the coal plate and/or hookah head connected to the drive wheel via the transmission is rotatable.

In a further advantageous development, a weight can be comprised in the drive part, wherein the weight can preferably be wound up by pulling a chain, in particular by a crank, comparable to a mechanical pendulum clock movement with a weight accumulator, e.g. a cuckoo clock movement. The weight can be provided as a mechanical energy storage device to store the mechanical or potential energy. The weight can be suspended from the chain, which preferably has a crank for winding. By pulling down the chain, a weight is pulled up such that the mechanical or potential position energy of the weight can be stored. The stored potential energy can be converted back into kinetic energy when the weight is lowered, thus allowing the drive wheel to rotate around the rotary shaft. Thus, the coal plate and/or hookah head can be rotated.

In a further advantageous development, an elastic band, for example a rubber band, can be provided as a transmission, wherein the drive device, preferably the drive wheel, is connected to the coal plate or hookah head by the rubber band. The drive device comprises the rotary shaft, the drive part and the drive wheel, wherein the drive part and the drive wheel are connected to each other via the rotary shaft. The elastic band can be attached to the axially extending lateral surface of the drive wheel and the coal plate, and thus the coal plate can Be rotatably coupled to the drive wheel.

In this case, the coal plate and the drive wheel rotate in the same direction. Alternatively, it is conceivable that the hookah head is designed in two parts, wherein the tobacco is accommodated in the upper part. The upper part can be designed as a rotatable section, while the lower part is designed to be fixed. By means of the rubber band, the upper part of the hookah head can be connected to the drive device, preferably to the drive wheel, such that the hookah head, in particular the upper part of the hookah head, can be rotated.

In a further advantageous development, an elastic roller, in particular a rubber roller, can be arranged on the axially extending lateral surface of the drive wheel, wherein the rubber roller is in direct contact with the coal plate or hookah head. In this case, the rubber roller is provided as a transmission, in order to operate the coal plate or hookah head. The drive wheel can be connected to the drive part by the rotary shaft, which drive part can be designed as an electrical drive or mechanical drive. In this way, the drive wheel is rotated. The ratio of the diameter of the rubber roller to the hookah head/coal plate influences the speed conversion. The rubber roller can be attached to the axially extending lateral surface of the drive wheel. By means of the rubber roller, a rotational movement of the drive wheel can be transmitted to the coal plate or the hookah head, such that the drive wheel and the coal plate or the hookah head can rotate in opposite directions.

In a further advantageous development, two gearwheels can be provided as a transmission, wherein the first gearwheel and the second gearwheel are each formed on the axially extending lateral surface of the coal plate and drive wheel. Thus, during operation, the teeth of the two counter-rotating gearwheels can mesh with each other. In this development, it is proposed that the first gearwheel is arranged on the axially extending lateral surface of the drive wheel and the second gearwheel is arranged on the axially extending lateral surface of the drive wheel, wherein both gearwheels contact each other in the rest position. The drive part allows the drive wheel to be rotated with the second gearwheel, and thus the first gearwheel can rotate in counter-rotation with the coal plate. Alternatively or additionally, the hookah head can comprise a rotatable section, wherein the first gearwheel is arranged on the axially extending lateral surface of the rotatable section of the hookah head. Thus, the rotatable section of the hookah head and the drive wheel can rotate in opposite directions.

In a further advantageous development, the drive device can be designed to rotate the coal plate and hookah head in opposition to each other at a controllable rotational speed of 20-35 rpm, preferably at a rotational speed of 25-30 rpm, in particular at a rotational speed of 26 rpm, wherein preferably the rotational speed of the drive device is adjustable. The drive device comprises the rotary shaft, the drive wheel and the drive part, wherein the drive wheel and the drive part are connected to each other by the rotary shaft. in this case, an electric motor can particularly advantageously be provided as the drive part. When a radius of the coal plate or hookah head is made larger than a radius of the drive wheel, a rotational speed of the electric motor larger than 20-35 rpm is required to reach the rotational speed of the coal plate or hookah head of 20-35 rpm, preferably of 25-30 rpm, in particular of 26 rpm. By adjusting the speed of the electric motor, the rotation speed of the coal plate or hookah head can be changed. This enables different amounts of vapour to be generated during smoking.

In a further advantageous development, the drive device can be arranged to terminate a relative rotation between the coal plate and the hookah head after a predeterminable time. In this development, it is proposed that the drive device can comprise a timing unit, wherein the timing unit has a controller. Furthermore, in this development, the electric motor can advantageously be arranged as a drive part, wherein the electric motor is connected to the time control unit. A predeterminable time can be defined in the controller. As soon as the time is reached, the electric motor is automatically disconnected from the power grid or from the rechargeable batteries. This stops the rotation of the drive wheel, such that the relative rotation between the coal plate and the hookah head can be stopped. Advantageously, even if time elapses, the rotational speed can be reduced to a standstill, i.e. the rotational speed can be slowed down further and further. In another advantageous development, the drive device can comprise a temperature sensor that can detect a temperature of the hookah head, and the temperature sensor is arranged to end a relative rotation between the coal plate and the hookah head upon reaching a predetemiinable first temperature, and/or to start a relative rotation when falling below a predeterminable second temperature. The temperature sensor can be arranged on the hookah head to measure the temperature of the hookah head or tobacco. Advantageously, an electric motor can be provided as the drive part, but a mechanical drive can also be used for this purpose. As soon as the predetermined first temperature is reached, the electric motor can be switched off. This can stop the relative rotation between the coal plate and the hookah head. In the start phase or when the temperature falls below a second, lower temperature than the first temperature, e.g. when the smoke flow is increased, a relative rotation can be started. It is advantageous that the temperature of the tobacco is controlled by the temperature sensor in order to generate any amount of steam and to avoid overheating or combusting of the tobacco.

In a further advantageous development, the drive device can be magnetically coupled to the coal plate or the hookah head. On the coal plate or hookah head, at least one ferromagnetic element or at least one permanent magnet, preferably several permanent magnets, can be arranged with a magnetic orientation as south pole or north pole. A further permanent magnet, preferably several permanent magnets, or optionally ferromagnetic elements or a set of current coils can be provided on the drive device, preferably on the drive wheel, as the north pole or south pole, wherein the permanent magnet/the ferromagnetic element of the drive device has a different polarity from a polarity of the ferromagnetic element/permanent magnet of the coal plate/hookah head. Current coils can, with suitable electric wiring, provide a magnetic rotating field with which the permanent magnetic element(s)/ferromagnetic element(s) of the rotatable coal plate or hookah head can be coupled. If the drive device is activated, the permanent magnet of the drive device or the magnetic field provided by it can rotate together with the drive wheel. Thus, the two permanent magnets or the pairing of permanent magnet/magnetic rotating field/ferromagnetic element attract each other according to their position. In this way, the coal plate/the hookah head can rotate in a magnetically coupled manner. Alternatively, a permanent magnet can be provided on the hookah head, wherein the permanent magnet of the hookah head has an opposite polarity to the permanent magnet of the drive device, such that the hookah head can be magnetically coupled and carried along. Advantageously, a contactless coupling can be achieved in this way, such that a decoupling between the drive device and the hot coal plate/hookah head occurs thermically. Thus, a thermal load on the drive device and thus a durability can be increased.

In a further advantageous development, the drive device can have a further rotation axis arranged along the same axis of rotation of the coal plate or the hookah head, wherein the drive device can drive an arm rotating around the axis of rotation as a driver of a magnet/ferromagnetic element magnetically coupled to the coal plate or the hookah head. In this development, the drive device can drive a rotating arm with rotation around the axis of rotation of the coal plate or hookah head. The extension arm has a permanent magnet or ferromagnetic element at its distal end. If the drive device is switched on, the arm can rotate around the axis of rotation of the coal plate/hookah head. A magnet held by the arm, preferably a permanent magnet or a ferromagnetic element, rotates around the axis of rotation of the coal plate/hookah head. Furthermore, a further magnet, preferably another permanent magnet or a ferromagnetic element, is arranged at the peripheral edge region of the coal plate or the hookah head. Due to a magnetic attraction between the permanent magnet of the drive device and the permanent magnet of the coal plate or the hookah head, the coal plate or hookah head can rotate with the arm of the drive device. In this way, a relatively simple and wear-free contactless coupling of the coal plate, which is very hot in operation, to a drive arm is achieved magnetically, wherein a comparable construction of the drive device as in the aforementioned exemplary embodiments can be used. This does not drive the coal plate/hookah head directly, but rather indirectly, by first driving a drive arm rotating around. the axis of rotation of the coal plate/hookah head.

In a further advantageous development, the hookah head or the coal plate can comprise revolving magnets with alternating polarity or one or more ferromagnetic elements, preferably on an outer periphery or a peripheral bottom or top surface, and the drive device can comprise a set of current coils which can generate a circumferential magnetic field, wherein the magnets/ferromagnetic element of the hookah head or the coal plate can attach to the magnetic field generated by the current coils. For this purpose, it is proposed that the coal plate or the hookah head has multiple magnets, in particular multiple permanent magnets, or one or several ferromagnetic elements, which are arranged on an outer periphery or on a bottom/top surface rotating around the axis of rotation of the coal plate or the hookah head. Furthermore, multiple grooves can be formed in the drive device, in which grooves the coils are arranged annularly peripherally, wherein the number of coils and the number of magnets can advantageously be the same. If the drive device is turned on, a current is alternately conducted in the coils in such a way that it results in a magnetic rotary field. In this way, revolving magnetic fields can be generated such that the magnets of the hookah head or the coal plate are attracted by the magnetic fields and can rotate with the drive device, or are induced in the ferromagnetic element in eddy current in such a way that a magnetic coupling is established, resulting in a rotary movement. In this way, an electric motor with the drive device as the stator and the coal plate/hookah head as the rotor can be used as a synchronous motor (in the case of permanent magnets) or as an asynchronous motor (in the case of ferromagnetic elements), such that a rotational movement is achieved in a contactless manner, and a thermal decoupling is made possible.

A particular embodiment of the hookah heat distribution device comprises a temperature controller, such as a thermostat, which is designed to keep the tobacco at a temperature which is as constant as possible or at least within a predetermined temperature range. Preferably, the temperature controller comprises a temperature sensor and a controller which drives the drive of the coal plate depending on the measured temperature. As the controller, a simple P-controller, for example, can be provided, but also any other type of controller. The temperature sensor can be installed, for example, in or on the hookah head, on the coal plate, in the chimney or in another place.

A hookah according to the invention can also comprise a communication interface, such as a Bluetooth interface, via which the hookah can communicate with mobile devices. By means of the interface, data, for example, of any type, or optionally also control commands can be transmitted.

In the figures, the same elements are provided with the same reference numerals. The figures show only examples and are not to be understood as limiting.

FIG. 1 and FIG. 2 show a side view and a plan view of a first embodiment of a hookah heat distribution device 10, which comprises a hookah head 12 comprising a base 64, a coal plate 76, a drive device 90 and a rubber band 42 as a transmission 92. A chimney attachment 32 is arranged on the axially extending lateral surface of the hookah head 12, which chimney attachment has a chimney pipe 22. This can be used to dissipate excess heat. The sieve 38 is provided as a coal plate 76, on which lighting coal is provided. Ambient air is heated by the lighting coals and enters the hookah head 12 through air inlet openings 36 of the surface 34 to heat the tobacco provided in the hookah head 12. A chassis 14 can be used to attach the hookah head 12 to the drive device 90, wherein the chassis 14 is attached to and aligned on the hookah head 12 by means of a fixing screw 18 and attached to and aligned on the drive device 90 by means of an adjustment screw 16. The drive device 90 comprises a rotary shaft 28, a drive wheel 78 and an electric motor 40 as a drive portion 96, wherein the drive wheel 78 is connected to the electric motor 40 by the rotary shaft 28. The electric motor 40 is equipped with a cable 24 having a plug 62. When the electric motor 40 is connected to the power grid, the drive wheel 78 rotates around an axis of rotation 94. The coal plate 76 is connected to the drive wheel 78 by means of the rubber band 42, such that the coal plate 76 can rotate around an axis of rotation 20, wherein the coal plate 76 and the drive wheel 78 rotate in a clockwise direction. Thus, the coal plate 76 is rotatable with respect to the hookah head 12. In this way, the tobacco received in the hookah head 12 can be heated homogenously.

FIG. 3 depicts a side view and FIG. 4 depicts a plan view of a second embodiment of a hookah heat distribution device 48. A drive device 90 comprises a rotary shaft 28, an electric motor 40 and a drive wheel 78, wherein the electric motor 40 is provided as a drive part 96. The electric motor 40 can be connected to the power grid by means of a cable 24, wherein the cable 24 has a plug 62. The drive wheel 78 is mounted on the rotary shaft 28, wherein the drive wheel 78 is rotated around the rotary shaft 28 or around an axis of rotation 94 by a motor drive. On a lateral surface of the drive wheel 78, a second gearwheel 46 is arranged, which has a plurality of tooth tips 70. In a hookah head 12, tobacco is heated by heated air that enters the hookah head 12 through air inlet openings 36 of the surface 34. A chimney attachment 32 having a chimney pipe 22 is arranged on the axially extending lateral surface of the hookah head 12, wherein the hookah head 12 has a base 64. Excess heat can be dissipated through the chimney pipe 22. A sieve 38 is provided on the hookah head 12 as a coal plate 76, on which coal lies. A first gearwheel 44 is mounted on the axially extending lateral surface of the coal plate 76, wherein in operation, teeth of the first gearwheel 44 and of the second gearwheel 46 engage with each other. Thus the first gearwheel 44 can rotate with the coal plate 76 around an axis of rotation 20, wherein both gearwheels 44, 46 rotate in opposite directions. Both gearwheels are formed as a transmission 92; the speed is dependent on the ratio of the number of tooth tips 70 of the gearwheels 44, 46. The chassis 14 is attached to the hookah head 12 and the drive device 90 by means of a fixing screw 18 and an adjustment screw 16, such that the hookah head 12 and the drive device 90 can be connected to each other such that there is also the possibility of retrofitting.

FIG. 5 and FIG. 6 show a side view and a plan view of a third embodiment of a hookah heat distribution device 50. On a hookah head 12 having a base 64, a sieve 38 is formed as a coal plate 76, on which lighting coals can be provided.

A chimney attachment 32 is mounted on the axially extending lateral surface of the hookah head 12 in order to dissipate excess heat through a chimney pipe 22. The coal plate 76 is connected to the drive wheel 78 via a rubber band 42, which is arranged as a transmission 92, During a rotation of the drive wheel 78, the coal plate 76 can thus rotate around an axis of rotation 20 with respect to the hookah head 12. Through air inlet openings 36 of the surface 34, the air heated by the coal can enter the hookah head 12. Hereby, during a relative rotational movement between the coal plate 76 and the hookah head 12, tobacco can be heated homogeneously.

By means of the gearwheels, a rotational movement of the drive wheel 78 can be transmitted to the coal plate 76. In other words, the coal plate 76 can rotate relative to the hookah head 12. Thus the tobacco is homogeneously heated by the coal. By using a chassis 14, the hookah head 12 can be connected to the drive device 90, wherein the chassis 14 is attached to the hookah head 12 by means of an adjustment screw 18 and to the drive device 90 by means of a fixing screw 16.

A drive device 90 comprises a rotary shaft 28, an electric motor 40 as a drive part 96 and a drive wheel 78. The electric motor 40 can be connected to the power grid by means of a cable 24, wherein the cable 24 has a plug 62. In a hookah head 12, tobacco is heated by heated air which enters the hookah head 12 through the air inlet openings 36 of the surface 34.

On the lateral surface of a base 64 of the hookah head 12, a roller bearing 110 having an arm 98 is mounted, which roller bearing is coupled to the drive wheel 78 by means of a rubber roller 80 as a transmission 92, such that the roller bearing 110 with the arm 98 can rotate around the axis of rotation 20, which is concurrently the axis of rotation of the coal plate 76 or of the hookah head 12. As a result of the magnet 100 held by the arm 98 and a magnet 100 arranged on the coal plate 76 being attracted to each other, the coal plate 76 can be magnetically coupled and thermically decoupled.

FIG. 17 and FIG. 18 depict a side view and a plan view of a ninth embodiment of a hookah heat distribution device 108, In a hookah head 12, tobacco is heated by heated air which enters the hookah head 12 through air inlet openings 36 of the surface 34. Furthermore, a chimney attachment 32 having a chimney pipe 22 is arranged, and excess heat can thereby be dissipated. The coal for lighting lies on a sieve 38, Magnets 100 with alternating polarity are arranged on an outer lateral surface of the coal plate 76. A drive device 90 having grooves, said drive device bearing a set of current coils 94, is annularly arranged to be distributed peripherally around the axis of rotation 20 of the coal plate 76, wherein a current through the current coils 104 is switched in such a way that a magnetic rotary field is established which moves annularly around the axis of rotation 20. A rotating magnetic field is thus generated, wherein the magnets 100 attached to the coal plate 76 are attracted by the magnetic field, such that the coal plate 76 and the drive device 90 can rotate in the same direction.

Alternatively, instead of magnets 100, one or more ferromagnetic elements can be arranged on the coal plate 76, such that a motor following the principle of an asynchronous machine can be provided. A control logic according to the principle of a multi-phase current controller is comprised in the drive part 96 in order to provide alternating current flows through the current coil 104. The drive part 96 is mounted on the lateral surface of a base 64 of the hookah head 12, wherein the control logic can be connected to the power grid via a cable 24. The drive part 96 with the current coils 104 acts as a stator of an electric motor, and the coal plate 76 with the permanent magnets 100 or ferromagnetic elements as a rotor of a synchronous or asynchronous machine. Due to the air gap between the rotor and stator, a rotational movement can be achieved in a magnetically coupled manner and simultaneously a thermal decoupling can be achieved.
